Abstract
A helical fixation element of an implantable medical lead. The fixation element has at least one blood drainage channel running along at least a tissue-penetrating portion of the helix windings of the fixation element. The channel guides, during penetration and anchoring of the fixation element and the lead in a tissue, blood leaking from the tissue away from the vicinity of the fixation element, thereby reducing the size of a fibrin clot formed around the fixation element. The capture threshold for stimulating the tissue is therefore reduced.
